**Name of the Vulnerable Software and Affected Versions**
DokuWiki versions 2016-06-26a and older
**Description**
The issue allows users to scan ports of internal networks via SSRF, affecting private networks such as 10.0.0.1/8, 172.16.0.0/12, and 192.168.0.0/16, when media file fetching is enabled. This is due to the `sendRequest` method in the `HTTPClient` Class in the file `/inc/HTTPClient.php` having no access restrictions.
**Recommendations**
For DokuWiki versions 2016-06-26a and older, consider disabling media file fetching to prevent SSRF attacks until a patch is available. Restrict access to the `sendRequest` method in the `HTTPClient` Class to minimize the risk of exploitation.
